(54) Brake rotor and method for producing same


(57) A rotatable vehicle brake component (10) having integrally formed teeth (22) adapted for use with a sensor of an anti-lock brake system is disclosed. The method for producing the rotatable vehicle brake component (10) of this invention comprises the steps of: (a) providing a vaporizable pattern having a shape which generally corresponds to the desired final shape of the rotatable vehicle brake component (10), the rotatable vehicle brake component selected from the group consisting of a vehicle brake drum and a vehicle brake rotor, the pattern ; (b) forming a mold around the pattern; (c) forming the rotatable vehicle brake component by a lost foam casting process wherein molten metal is introduced into the mold causing vaporization of the pattern, the rotatable vehicle component (10) having integrally formed teeth (22); (d) removing the cast rotatable vehicle brake component (10) from the mold; and (e) machining the integrally formed teeth (22) of the cast rotatable vehicle brake component to predetermined tolerances to thereby produce the rotatable vehicle brake component (10).
